Pericardial drainage operations in the management of uremic pericardial effusion.

Because of frequent failures in nonoperative therapy, we have adopted early surgical drainage of the pericardium in the management of uremic pericardial effusion. This series presents the longest follow-up period of any group of patients with uremic pericardial effusion treated by surgical drainage. There have been no intraoperative deaths and no recurrences. The total hospital mortality rate was 8.3 per cent and the late mortality rate over a 72 month period was 25 per cent. Internal pericardiostomy drainage is a simple yet effective surgical solution to the life-threatening problem of uremic pericardial effusion.

Injuries to the phrenic nerve resulting in diaphragmatic paralysis with special reference to stretch trauma.

Traumatic interruption of the phrenic nerve causing diaphragmatic paralysis occurs much more commonly than realized. Patients present with symptoms referable to the respiratory, gastrointestinal, or cardiovascular systems as a result of anatomic displacement of the respective organ (eventration). Symptoms often occur shortly after the injury but may be delayed for many years; consequently, prolonged follow-up of these patients is essential. If patients are symptomatic after trauma, judicious observation is dictated, since many will experience gradual return of normal diaphragmatic function over the succeeding six to twelve months. In those who remain significantly symptomatic, thoracotomy and imbrication of the eventration is a simple and effective surgical procedure.

Surgical significance of the endothoracic fascia. The anatomic basis for empyemectomy and other extrapleural technics.

Attention if directed to explanation of the endothoracic fascia in several operations described by pioneer thoracic surgeons. The extrapleural plane was extensively and successfully employed in a number of these operations. Re-emphasis of its use seems advisable even today when open thoracotomy is the rule rather than the exception. In selected cases the extrapleural plane can and should be dissected in the aggressive management of relatively localized empyema, with complete enucleation of the infected sac (empyemectomy). This operation can reduce morbidity and prevent prolonged external drainage. The surgical advantage of the extrapleural plane is also apparent in complete parietal pleurectomy for effective palliation of repeated fluid formation. Other instances of intrathoracic disease are mentioned for which dissection in the extrapleural plane can be a safe and time-saving method of treatment. The anatomic considerations relating to the rapid, safe, and effective dissection of the major hilar vessels are also emphasized.
